The 500ml Ultraflask is a collapsible sport bottle with a versatile bite valve. Perfect for runners as it's clean, compact and easy to use.  

Hydrapak says:

Part of our ultra-light series, the 500 ml is so light, you might forget you brought it. Weighing in at just over an ounce, it’s optimal hydration, no matter what kind of runner you are. Its pliable material conforms to most pockets, it shrinks as you drink to minimize water movement and it can be used with or without the tube. Ultra light weight, ultra useful.

Hydrapak's 500ml Ultraflask is perfect for use with running vests and packs. The long tube allows you to access your drink without removing the flask when used in chest/shoulder straps.

The bite valve can also be used without the tube and mounted straight on to the cap for hand held use.

Not only does the flask collapse for storage, it actually collapses as you drink, preventing that annoying sloshing when your on the move.

Great piece of kit

This is a great little piece of kit. It is light weight, collapses when empty and is 100% taste neutral and odourless. The opening is wide enough indeed to allow for ice cubes to pass through without hassle. It comes with both a regular cap and a cap with a straw attached to it, BOTH of which are fitted with a detachable valve. Nice. The straw, for me, was the right length as delivered, those who need a shorter straw can easily cut it down to size. It fits my vest very nicely. I believe it will fit most vest pockets, since the shape is so adaptable. I highly recommend!
